Once you've done the above you should now be able to run the tools from the command line like so:

On Linux / Mac

sparql --version

On Windows

sparql.bat --version

This command will simply print the versions of Jena and ARQ used in your distribution, all the tools support the --version option. To find out how to use a specific tool add the --help flag instead.

Note that many examples of using Jena tools typically use the Linux style invocation because most of the Jena developers work on Linux/Mac platforms. When running on windows simply add .bat as an extension to the name of the command line tool to run it, on some versions of Windows this may not be required.
